Eben Freeman’s foamy interpretation of eggnog—infused with the sweet, caramelly flavors of sticky toffee pudding, a British favorite—is halfway between a drink and a dessert. "It’s thick enough to eat with a spoon," he says. "So was classic eggnog."

Scott Marshall, principal bartender at Drink in Boston, came up with this rich, spicy after-dinner drink. "I love flips," he says of the category of cocktails that contain a whole raw egg. "The egg adds a velvety creaminess that surprises most people."
